GUSTARD DAC-X26pro Balanced DAC Decoder Bluetooth 5.0 Audio DAC Two ES9038PRO For MQA Full Decoding

GUSTARD DAC-X26pro Balanced DAC Decoder Bluetooth 5.0 Audio DAC Two ES9038PRO For MQA Full Decoding

Advantages:
- ES9038PRO dual core
- Synchronous clock implantation technology reduces audio source clock requirements
- 10M clock input, K2 ultra-low noise synthesizer
- DSP autonomous digital filtering reduces aliasing noise
- For XMOS, DSD512, PCM768K, MQA full decoding
- CPLD programmable logic chip
- Bluetooth 5.0
- Support for LDAC HD audio transmission
- Digital filtering: 3 kinds of PCM, 4 kinds of DSD, support for NOS mode
- ES9311Q multiple independent power supplies, abundant energy
- IIS-H input
- Fully balanced: without any conversion, complete four-way output
- Analog LPF circuit, discrete Class A design
- Full function remote control 0dB to -90dB

Features:
- Two flagship chips ES9038PRO are used for decoding, each of the left and right channels, completely independent power supply, independent grounding, to obtain the best performance
- K2 ultra-low noise clock
- K2 Synthesizer Synchronous Clock Implantation Technology: Provides local femtosecond clock and external 10M clock frequency to synthesize the master clock, and then synchronize implantation and decoding. The front-end clock is discarded, and the DAC only uses a local femtosecond clock or an external thermostat clock. Therefore, the front-end clock performance greatly reduces the impact of the decoding link, reducing the system's dependence on the performance of the front-end audio equipment. The effect is that USB, IIS, AES, coaxial, optical fiber, and Bluetooth can all enjoy the improvement brought by local femtosecond or external 10M clock
- Hybrid discrete IV conversion circuit, independent parallel circuit, fully meet the requirements of 9038 large current
- Analog LPF circuit, especially for fully discrete Class A circuits debugged by 9038 chip
- The new design module integrates function and performance. For ARM microprocessor, DSP processor, Bluetooth 5.0, CPLD programmable chip, large-capacity memory, for XMOS XU216
- CPLD programmable logic chip: self-constructed digital integrated circuit with logic function, clock management, 2nd PLL digital shaping, DOP demodulation, PCM/DSD depop switch and other exclusive technologies, help you create excellent sound quality
- DSP digital filter: This solution is a high-performance digital filter solution developed on a dedicated DSP platform for digital audio. It is equipped with a self-developed high-performance anti-aliasing noise algorithm. The key digital signal processing links use high-precision floating-point 64bit. Operation. To reduce the aliasing noise in the digital domain audio band, that is, to achieve better sound quality performance by upscaling and noise shaping the original digital audio stream signal. PCM: VIVID (recommended) /COMPO SITE/GENTLE; for NOS mode: do not perform digital over-sampling, directly perform analog conversion on the original signal
- USB uses AUDIO dedicated chip XU216 for XMOS
- Support PCM768K, DSD512
- CSR8675 chip, support Bluetooth 5.0, for LDAC, AAC, SBC, APTX. For LDAC 24bit 96KHz HD transmission
- Two high-quality audio dedicated toroidal transformers supply power to the digital and analog respectively, without interfering with each other
- Independent voltage stabilization, multi-stage filtering, left and right separation, no mutual interference
- Multiple sets of power supplies, no interference with each other, abundant energy
- Rigorous design, reasonable layout, neat workmanship, premium components

Package Included:
- 1 x Set of Decoder
